ATTACHMENT FOR WOOL-COMBING MACHINES.

SPECIFICATION forming part of Letters Patent No. 532,217, dated January 8, 1895.

Application filed August 15, 1894:. Serial No. 520,371- (N model.)

To all whom it may concern.-

Be it known that we, HENRY SMITH, a subject of the Queen of Great Britain and Ireland, residing at Fitchburg, in the county of Worcester and State of Massachusetts, and JOHN DE VRIES, a citizen of the United States, residing at Passaic, in the county of Passaic and State of New Jersey, have invented certain new and useful Improvements r o in Attachments for Wool-Oombing Machines, fully described and represented in the following specification and the accompanying drawings, forming a part of the same.

This invention relates to that class of wool .15 carding or combing machines wherein the carding operation is performed by the action of a large combing circle with one or more smaller circles inclosed within the same and geared to rotate in a position tangent thereto; 29 the outer circle being supplied with the wool by a concentric series of feeding boxes for depositing thereon the wool which is pressed upon the pins or teeth of the circle by suitable means adjacent to the smaller circles.

The present improvement consists in certain details of construction hereinafter set forth and described.

The invention will be understood by reference to the annexed drawings, in which Figure 1 is a front elevation of the attachment applied to one of the columns of a circle combing machine, showing a portion of each of two tangential combing circles. Fig. 2 is a side elevation of the same; and Fig. 3 5 5 is a plan of the same with the outlines of the circles indicated in dotted lines. Fig. 4 is a face view and Fig. 5 a longitudinal section of the inner presser wheel; and Figs. 6 and 7 are similar views of the adjacent presser wheel. Fig. 8 is an elevation, upon a larger scale, of the presser wheels and their respective spindles formed directly with the coupling members at their adjacent ends, the said wheels and a portion of one of the spindles being in section at the center line.

The outer combing circleA is provided upon its upper face with the projecting pins or teeth 25 and is mounted upon a ring B having internal gear teeth. The inner combing cir- 5o cle a is similarly provided with comb teeth 25' and is mounted upon an externally toothed ring b meshing with that of the outer circle. Each of these toothed rings is mounted upon a hollow ring 0 0, respectively, through which steam is circulated to retain the said members 5 in a heated condition while in operation upon the wool.

The smaller circle'a is in practice journaled about the vertical column d through which is extended a shaft for communicating power from an overhead driving shaft to the actuating mechanism below the table of the machine. To this column we afiix the bracket e, projecting radially therefrom and carrying the presser mechanism, by means of the bolts e inserted through the vertical slots e in the foot which are provided for the vertical adjustment of the device. The under side of this bracket is provided with ribs along the edges between which are fitted the feet of the bracket bearings f f, respectively, in which are mounted the spindles g, h, h and stud '1; transverse to the circles and adjacent to their pointof contact.

As indicated in Figs. 1 and 3, the spindle h is mounted in the outer bracket bearing f radial to the large combing circle A, and carries two toothed disk presser wheels m n, the lower sides of which project between the rows of teeth t of the circle A; and the spindle h is mounted similarly in the bracket bearing f radial to the smaller combing circle a, and carries a toothed disk presser wheel n similarly penetrating between the rows of comb teeth 25' of the circle a. Each of such presser 8 5 wheels is slightly cupped, and its spindle is in consequence suitably inclined from the horizontal, in order that it may conform substantially to the curvature of the concentric rows of teeth upon its respective circle.

The spindle g is mounted a little above and in advance of the spindles h and h, and carries the preferably toothed guiding ordelivering wheels Z, their lower edges being a little above the tops of the comb teeth of the circles 9 5 and their adjacent edges projected slightly between the wheels m, n and 71' upon the spindles h and h, respectively.

To couple the spindles h and it together, the presser wheel at is provided upon its in- [00 nor face with an integral internal gear 0, and the outer face of the wheel n is provided similarly with a spur gear 0 adapted to project within the said gear 0 and to mesh therewith, thereby forming a flexible coupling between such members. In lieu of such means of coupling the two spindles together, it may be found preferable 'to employ the expedient illustrated in Fig. 8; wherein thecontiguous ends of the spindles are formed directly with the intermeshing gears 0 and 0. It will be observed, however, that in either case the intermeshing gears at the ends of the spindles form a desirable coupling therefor, as they occupy a minimum space between the adjacent presser Wheels where other forms of coupling would be found too large.

The inner end of each of the spindlesg and h carries a gear '2" and the stud '23 is provided with a simi ar intermediate gear 0" meshing with each of the gears r and causing their respective spindles to rotate in the same direction with relation to the circles. The spindle g carries in addition a sprocket wheel 8 connected by means of a chain .9 with a similar wheel .9 sustained by the bracket to which is bolted to the bracket 6; and such sprocket wheel 3 is in turn actuated from the driving pulleyp, mounted upon the adjustable slotted arm '11 secured upon the bracket 16, by means of a pair of change wheels q mounted to rotate with the pulley p and the sprocket wheel .9 respectively.

As the pressing m echanism illustrated h erein is designed to be actuated separately from the combing circles, the change wheels q are provided to furnish a means of adjustment for the speed of the presser and delivery wheels to the surface speed of the circles,

whatever maybe the speed at which it may be convenient to drive the pulley 19.

Although the delivery and presser wheels of both series are shown herein with teeth in their peripheries in order to grasp the wool more positively as it issues from the feeding boxes, We have found in practice that the teeth in the former may be readily dispensed with, and that those of the presser wheels are not absolutely necessary to the efficient operation of the device, although they add somewhat to the effectiveness of such wheels. It will be found preferable in practice that the teeth in the presser wheels should be inclined in the direction of their rotation as indicated in the drawings, in order that there may be the least tendency to carry any wool around with them after having pressed it between the comb teeth; and such liability is still further lessened, as to both series of wheels, by the slight interlocking of the same as indicated in Figs. 2 and 3, whereby each series serves to guard against such action in the other by the rotation of their adjacent sides in opposite directions.

teeth 6 t, and the further rotation of the circles brings such wool under the presser wheels which in their turn force the same downward upon the circles over the teeth, whence it is drawn upon the smaller circle and subsequentlystripped therefrom by suitable means.

In Fig. 8 the spindles are shown each threaded over a portion of their length to receive the internally threaded hubs of the presser wheels 'm n n, which may in practice be locked in place against suitable shoulders formed directly upon their respective spindles for the purpose or presented by collars applied to such threaded portion of the spindle, as the collar 00?, which serves also to space the presser Wheels m and it apart in the desired degree upon the spindle h. Additional collars h are shown at the outer ends of the spindles for holding the spindles from movement endwise in their respective bearings.

Having thus set forth the nature of ourin vention, what we claim herein, and desire to secure by Letters Patent, is

1. In a circle wool combing machine, the combination, with two of the tangential combing circles, of an inwardly inclined spindle carrying one or more dished presser wheels mounted radial to and directly above the outer combing circle and beyond its point of tangencywith the inner circle, a second inwardly inclined spindle mounted radial to and directly above the inner tangential combing circle and carrying one or more dished presser wheels, the said spindles being coupled together at their adjacent ends and means connected with one of the spindles for rotating the presser wheels with the combing circles, as and for the purpose set forth.

2. In a circle wool combing machine, the combination, with two of the tangential combing circles, of an inwardly inclined spindle carrying one or more dished presser Wheels mounted radial to and directly above the outer combing circle and beyond its point of tangency with the inner circle, a second inwardly inclined spindle mounted radial to and directly above the inner tangential combing circle and carrying one or more dished presser wheels, the said spindles being coupled together by means of intermeshing internal and external gears at their respective adjacent ends, and means connected with one of the spindles for rotating the presser wheels with the combing circles, as and for the purpose set forth.

In testimony whereof we have hereunto set our hands in the presence of two subscribing witnesess.
